REWIND SHAFT.

Application filed April 30,1927. SeriallNo. 187,805. y

rlhis invention relates to supporting shafts especially such as are used for rolls of fiexible material having hollow cores in winding or other machines. Some of the machines of this type are rather large and the flexible material very wide and consequently the shaft which supports the roll of flexible material is very long and heavy rendering it difficult to handle so much so that an excessive amount of time'and effort are required to manipulate the shaft and roll.

The main object and feature of this invention is to produce a construction that .will render the supporting means for the roll less heavy and more easy to manipulate. In the accompanying drawings' the invention is disclosed in several concrete and preferred forms in which:

Fig. lis a longitudinal sectional view of a supporting means showing one form of the invention. Fig. 2 is a transverse sectional view substantially'on the plane of line 2-2 of Fig. l. Fig. 3 is an enlarged detail sectional view substantially on the plane of line 3-3 of Fig. l.

Fig. 4 is a perspective view of a bridging and spacer member that may be employed in connection with the invention.

Fig. 5 is a perspective view of the shell forming a part of the invention.

Fig. 6 is a view similar to Fig. 1, but showing a modied form of the invention.

Fig. 7 is a transverse sectional view subo stantially on the plane of line 7--7 of Fig. 6.

Fig. 8 s a detail view similar to Fig. 3 but showing a still further modification.

Fig. 9 is a view similar to Figs. 1 and 6 howing a modified form of connecting mem- Fig. 10 is an enlarged sectional view sub- :stantially on the plane of line 10-10 of .lgindicates a shell which may be of any suitable material and adapted to form a hollow core for a roll of flexible material. 2 and 3 indicate two chucks that extend into the ends of the shell and which, by reason of anges 4 and 5, engage the ends of the shell. Extending through the shell between the chucks is a connecting member 6, which may be a light rod or wire, but which perferably is a chain as shown in Figs. 1 and 6, a rope as shown' in Fig. 8 or a set of linked bars as shown in Figsf9 andlO. One ofthe chucks, here 3, is provided with a sleeve 7,

that carries flange 5, andthis sleeve is inter nally threaded as at 8. 9 indicates threads on chuck 8 to engage threads 8, andv 10 is a squared extension on chuck 3 for the reception of a wrench. It will now be understood that the connecting member is run through the shell and the chucks are inserted in the ends` of said shell. Then, by turning sleeve 7 flanges 4 and 5 will clamp the endsof the shell and will render the connecting member taut. Lock nuts, as 1l, may then be employed to retain the parts in position.' By

these means an assembly is produced rthat is much'lighter than a shaft, and it will be are wound in side by side relation then the shell may be in several parts or consist of several cylinders arranged end to end. In Figs. 1 and 6 there are two such cylinders and in Fig. 9 three are shown. In such cases it is advisable to use a hollow bridg` ing member 12 that straddles or spans the joint between adjacent cylinders, and such bridging members are provided with a spacer member 13 that 'extends between adjacent cylinders and cooperates with the chucks to clamp the parts in position.

If desired, a spring 14, anchored at opposite ends on the two chucks may be utilized as a guide to facilitate the assembling l of the parts, (see Fig. 6) and in this case also sleeve 7 may have wrench sockets 15 to effect the clamping operation. I claim: i 1. A supporting shaft including: a shell composed of a plurality of cylinders ar# ranged end to end, two chucks, one at each end of the shell, to engage the ends of the shell, a hollow bridging member within the shell to straddle the joint between two adjacent cylinders, a `spacing member on said bridging member to engage the ends of two adjacent cylinders, and means, including a flexible connecting member extending through the shell, between the two chucks to cause said chucks to clamp the shell endwise.

2. A supporting shaft including: a shell composed of a plurality of cylinders arranged end to end, two chucks, one at each end of the shell, to engage the ends of the shell, a hollow bridging member within the shell to straddle the joint between two adjacent cylinders, a spacing member on said bridging member to engage the ends of two adjacent cylinders, a l flexible connecting member between the two chucks'extending through the shell and bridging member, and means, associated with said chucks, to render the flexible connecting member taut and to cause said chucks to clamp the shell endwise.

3. A supporting shaft including: a shell composed of a plurality of cylinders arranged end to end, two chucks, one at each end of the shell, to engage the ends of the shell, a hollow bridging member within the shell to straddle the joint 'between two adjacent cylinders, a spacing member on said vbridging member to engage the ends of two adjacent cylinders, means, including a vflexible connecting member extending through the shell, between the two chucks to cause said chucks to clamp the shell endwise, and a spring within the shell surrounding the connecting member and anchored on the two chucks.

t. A supporting shaft including a shell composed `of a plurality of cylinders a1'- ranged end to end, two chucks, one at each end of the shell, to engage the ends of the shell, a hollow bridging member within the shell to straddle the joint between two adjacent cylinders, a spacing member on said bridging member to engage the ends of two adjacent cylinders, `a flexible connecting member between the two chucks extending through the shell and bridging member, means, associated with said chucks, to render the flexible connecting member taut and to cause said chucksto clamp the shell endwise, and a spring within the shell surrounding'the connecting member and anchored on the'tWo chucks.
